TS9011
Taiwan Semiconductor
250mA Low Quiescent Current CMOS LDO
DESCRIPTION
TS9011 is a positive voltage regulator developed
utilizing CMOS technology featured very low power
consumption, low dropout voltage and high output
voltage accuracy. Built in low on-resistor provides
low dropout voltage and large output current. A 1µF
or greater can be used as an output capacitor.
TS9011 are prevented device failure under the worst
operation condition with both thermal shutdown and
current fold-back. These series are recommended for
configuring portable devices and large current
application, respectively.
